Abstract

The invention discloses a dyeing method for textile fabric. The method includes the steps that firstly, a textile fabric basic body is dipped in hot water for certain time, then taken out, dried, thendipped in desizing liquid for certain time, taken out and dried, so that pretreated textile fabric is obtained; then, the pretreated textile fabric is put into a dyeing system to be dyed, the dyed textile fabric is transferred into a reaction kettle, next, carbon dioxide is introduced into the reaction kettle, the pressure of the reaction kettle is controlled to be 8-15 MPa, and the temperature of the reaction kettle is controlled to be 35-40 DEG C so that fluid in the reaction kettle can be supercritical carbon dioxide fluid; after color developing and fixation are conducted on the textile fabric in the reaction kettle for 2-3 hours, pressure relief is conducted on the reaction kettle, the reaction kettle is opened after pressure relief is completed, and the textile fabric is taken out after color developing and fixation. In combination with supercritical carbon dioxide, color developing and fixation are conducted, in this way, in the whole process of dyeing, the complexity is lowered greatly, dyeing quality is easy to control, and the dyeing system does not need to be cleaned.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a method for dyeing textile fabrics. Background technique [0002] Most of the traditional fabric dyeing adopts water dyeing process, but the water dyeing process needs to consume a lot of water resources on the one hand, and on the other hand produces a large amount of waste water which seriously pollutes the environment. Therefore, the water resource consumption and wastewater discharge in the printing and dyeing industry have seriously restricted the national sustainable development strategy and the development of the printing and dyeing industry, and seriously affected the quality of life of the people. [0003] In recent years, the research on supercritical fluid printing and dyeing technology has gradually attracted people's attention. Supercritical fluid dyeing technology uses a certain fluid to have a strong swelling effect on fibers in a supercritical state and ...
